Re: [wirelesslan] finding signal strength

Airopeek has got a solution similar to distributed
sniffer where the nodes can be deployed remotely and
they report back to a mother Node ie aka. laptop with
Airopeek.
The hardware at each node calculates and reports the
RSSI or signal strength of the frames it receives.
-Alternatively if you have got the source code for the
Mobile units wireless driver/firmware, you can modify
the drivers to sync up in time (Network time
server)and report RSSI instantaneously to a log.

Hope this helps.
